A Spring Pin, also known as a roll pin or tension pin, is a type of fastener used to secure two or more components together. It is a cylindrical metal pin with a slot or groove along its length, which allows it to compress and expand when inserted into a hole.Attributes:• Ensures proper alignment and prevents unwanted movement or misalignment• Tension and resilience of the spring pin enable accurate actuation, thus optimizing the performance• Distributes forces evenly between connected components, reducing the risk of localized stress concentrationsApplications:A Spring Pin is used to actuate or control the movement of the shut-off valve in the air inlet and exhaust system.
